Is the Secret Room footage on delay?

The footage that Sid and Paras watch seems pretty decently chopped up and edited. Not only do they watch what's going on, but there are camera switches and reaction shots of others too. Are they watching footage on slight delay? Or are the live cam operators really working so hard 24/7? If they really are watching live then that's a HUGE accomplishment 👏.

Just one preplanned event, or a football/cricket match is one thing, but to so seamlessly and smoothly show live footage 24/7 with camera cuts and live mic switches (only turning on relevant personal mics) is really cool. Underrated behind the scenes.

EDIT: I just realized in the task tomorrow as per the precap these guys give housemates instructions live. So, I guess their footage really is live? Or maybe only that part. Anyone know?
